Which of the following is a characteristic of thez-test?
Construct a 93% confidence interval for a sampling distribution that has means of {4, 4,4, 4.2, 4.2, 4.3, 4.3, 4.3, 4.4, 4.4, 4.4, 4.4, 4.5, 4.5, 4.6, 4.7, 4.7, 4.7, 4.8, 4.8, 4.8, 4.9,4.9, 4.9, 4.9, 5, 5, 5, 5, 5, 5, 5.1, 5.1, 5.1, 5.2, 5.2}. The standard deviation of thepopulation from which these samples were drawn was known to be= 0.357.ơ
As the confidence level increases for the same sampling distribution, the confidenceinterval __________.
